VECTOR CONTROL

When the FR-A8TP is mounted on the FR-A800 series, full-scale vector control operation can be performed using a motor with
encoder. The speed control, torque control, and position control can be performed by vector control. (For the details, refer to
the Instruction Manual (Detailed) of the inverter.)
